in Spain,) of which the following is a specification.

My invention relates to certain improvements applied to lamps in which acentral current of air is supplied to the burner; and

it consistsin the general construction, combination, and arrangement ofparts, as hereinafter described, and illustrated in the accompanyingdrawings, in which- Figure 1 is a sectional elevation of a lampembodying my improvements; Fig. 2, a sectional plan of the same throughthe wick-tubes; Fig. 3, a similar View to Fig. 1, but illustrating amodification of the air duct-and chamber; Fig. 4, a sectional plan ofthe same. Fig.

5 is a sectional view through the cap and airdiffuser detached. Fig. 6is a similar View, but with the flange of the cap bent at an acuteangle. Figs. 7 to 9 illustrate the application of my improvedair-chamber to suit two or 5 more flat wicks and of varying forms; and

Figs. 10 to 13 represent various forms of my air-chamber and diskadapted to round or cylindrical wicks.

A indicates the reservoir; B, inner wicktube; 0, guide for same; D,central air-duct; (Z, wings for supporting same; E, disk or button; F,air-chamber; f, perforationsin same; G, cap for wick; g, flange orprojection formed upon upper end of cap G; H, winding mechanism forwick; I, cover for protecting same; K, support for chimney; L, galleryfor globe.

In Figs. 1 and 2 it will be seen that I take a part of the centralcurrent of air by means of a tube, D, suited to the size of the burnerand fitted in the center thereof. By this tube D, the part F of which isperforated laterally and closed at its upperend, Ibring the specialcurrent of air up to a convenient height and distribute it, heated to ahigh temperature, by the holes f, perforated laterally, to all points ofthe flame; or I take the air intended for the chamber F fromperforations made in the disk E, in this case the tubeD serving assupport, and the air-duct is replaced by a solid support.

F is essentially a special chamber of suitable shape, open toward thebottom to receive a part of the central current ofthe burner, closedatits upper end,and perforated laterally,whatever may be theshaperounded, straight, or tapered-of the upper closed surface of thesame.

In burners having two or three flat Wicks I obtain the desired result,as shown, Figs. 7, 8, and 9, by means of a cap slit above the wicks,which, by the solid part preserved between the flames and by theparticular shape of this solid part, divides and projects the centralcurrent of air upon the burning gases. I place upon the cap G,-betweenthe flames, an air-chamber, F, receiving part of the central current ofair and distributing it heated bythe holes f to every part of theflames.

In Figs. 10, 11, 12, and 13 I show several arrangements in combinationwith a button, E. This button E is soldered on the tube D at the base ofthe air-chamber F, and is intended to spread or divert toward the gasesin combustion the'part of the central current of air not taken forth eaforesaid air-chamber. This button E niay be of a flat shape; but Iprefer and claim as novel the shape concave toward the bottom-conical orroundedas being superior to the old shape, in that this concave button Ebends the currentback toward the burning gases more powerfully and at asharper angle than the flat shape, and that there is obtained thereby asufficient enlargement or spreadingof the flame with a button E of lessdiameter. I

I may use the ordinary cap with rounded or conical top in combinationwith my air chamber or diffuser F and concave button E; but the form ofcap shown on the drawings will more forcibly divert the outer current ofair upon the gases in combustion, and I propose to use this cap G withflange 9 at right angle, as in Fig. 5, or at acute angle, as in Fig. 6,in combination with my air-chamber F and my concave-disk button 13.

Having fully described my invention, what I desireto claim and secure byLetters Patent 1. In a cenlraldraft lamp, the combination, with suitablereservoir and draft and wick tubes, of a laterally-perforated airconveying and heating chamber provided with a flange or disk secured tothe exterior thereof below the air-heating perforations, the said airheating and conveying device being located above the top of the draftand wick tubes, as set forth.

2. 111 a eeutral-draftlamp, the combination, with suitable reservoir anddraft and wick tubes, of a laterally-perforated air conveying andheating chamber provided with a concave disk secured to the exteriorthereof below the perforations through which the heated air passes tothe flame, the said air heating and conveying device being located abovethe top of the draft and wick tubes, substantially as shown anddescribed.

In a central-draft lamp, the combination, with suitable reservoir, draftand wick tubes, and the imperforate flanged cap G'r, ofalaterally-perforated air conveying and heating chamber located above andconnected with the d rafttube, and provided with the concave but ton E,permanently fixed below the air-heating perforations of said chamber,substantially as shown and described.

In testimony whereof I have hereunto set my hand in presence of twowitnesses.
